From what i hear, I think that light peek should be able to crush usb 3.0. The only thing is, I KNOW my keyboard or mouse won't need to use either usb 3.0 OR light peek. I have a feeling that USB 2.0 will stick around for a long time because manufacturers will find that they can get all the speed they need for a mouse or keyboard through it.
As for light peek and 3.0? I see 3.0 being rolled out quite soon and that light peek will come out soon thereafter and it will be used for hard drives and crap. I see the industry might get one port for all these technologies and we will see that manufactures will be using the cheapest and lowest costing technology they can, unless they feel they can make more money using a higher speed. For example, for a computer mouse we will still be using USB 2.0, for connecting my printer to my computer we will be using USB 3.0 and for using an external HDD we will use light peek. That's what I see happening.
